To all whom it may concern:

Be it known that I, FRANK ARCHER, a citizen of the United States,residin at Erie, in the county of Erie and State of ennsyl- Vania, haveinvented certain new anduseful Improvements in Wheel Rims,-of which thefollowing I is a specification.

This invention relates to wheel rims'and more particularly to automobiletire rims of the collapsible type wherein there is provided a hingatlsection which is adapted to be swung inwardly to facilitate applying andremoving the tire.

An important-object of the present invention is to provide a rim of theabove mentioned character which ischaracterized by simplicity inconstruction and operation.

A further object of the invention is to provide such a device havingnovel means of extremely simple construction for locking the hingedmember in normal position.

-Other objects and advantages of the invention will be a parent duringthe course In the drawings, I have shown one embodiment of theinvention. In this showmg Figure 1 is a side elevation of a rimembodymg. the invention,

Figure 2 is a fragmentary plan view of the inner face of the rim showingthe lockin mechanism,

igure 3 is a fragmentary perspective view of the free ends of the. rimin collapsed position,

Figure 4 is a detail perspective view of the pivoted locking member,

Figure 5 is a section taken on line 5-5 of Figure 2, and,

Figure 6 is a similar view taken on line 6-6 of Figure 2. Referring tothe drawings, the numeral 10 designates a rim of any standard type,shown in this instance as being of the straight side type. The rimcomprises a relatively stationary section 11 and a movable section 12.As shown, the movable section consists of approximately one-third of theentire rim length but the invention is not. limited to the particularproportions of the two rim sections. One end of the movable section 12is connected to the stationary section by a hinge 13 of any suitable orpreferred construction.

- A locking plate 14 is connected to the free greater portion of the wirivets or the like 15 which are counter-sunk upon the outer face of therim, as clearly shown in Figure 5. The outer end 16 of the plate 14projects a substantial distance beyond the free end of thehinged section12 and is provided upon its outer end with a beveled face 17 extendinthroughout the th of the plate and terminating at one side in a shoulder18 for a purpose to be described. Outwardly of the beveled face 17, theplate 14 is provided with a transverse lugv or projection 19 whichcooperates with other elements of the device to be described to effectthe looking of the sections of the rim.

As clearly shown in Figures 1, 2 and 5,.

12 of the rim is in closed position, as clearly shown in Figures 5 and6. A lockingmember 22 is pivotally connected adjacent the free end 0 therim section 11 by means of a rivet 23 intermediate its ends. The lockingmember is preferably slightly tapered as shown and is provided beneathits wider end' with an undercut eccentric cam face as shown in Figures 4and 5. One edge of the locking member 22' is beveled as at 25 for apurpose to be described.

The operation of the device is asfollowsz.

When it is desired to place a tire upon the rim, the free end of thehinged rim section 12 is swung inwardly to'any desired position as shownin Figure 1. The tire is then placed on the rim in the usual manner and,with the parts substantially in the position shown in Figure 1, the footof the operator may be pressed downwardly upon the free end of thehinged rim section until the lug 19 snaps into engagement within theopening 21. The lug'19 and opening 21 are preferably of the same sizeand shape whereby lateral movement of the free ends of the rim sectionsis effectually prevented as well as inward arcuate movement of the freeend of the hinged section. The locking member 22 is then turned by handuntil the cam face 24 engages the bevel face 17 I of the plate 14. Thefree end of the lock-- ing member 22 then may be tapped with a hammerupon-the edge adjacent the beveled portion 25 until the opposite end ofthis edge en ages against the shoulder 18 which limits t e turningmovement of the locking member. ,The rim is then placed upon the fellyof the wheel in the usual manner.

,To remove the tire, the locking member may I in Figure 1. The bevelface 25 permits the end of the hinged section-to be swung inwardlywithout interference bythe locking member. The tire then is removed inthe usual manner, a new tire replaced and the hinged section 12 againlocked in position in the manner previously described.

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes in the shape,

size, and arrangement of parts may be resorted to without departing fromthe spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, 1 claim: r rim comprising a air ofsections hingedly connected to provlde a pair of rel- 'atively movableends, said ends being beveled whereby oneis adapted to be swunginwardly, one of said ends bein provided with a transverse o ning, a 100'ng member pivoted interme iate its ends to said last named end adjacentsaid opening, said lock- 'ing member bein provided with an arcuateunder-cut bevele cam faceiadapted in one position to be arrangedopposite said opening, and a plate carried-by'the other of said ends andprojecting therebeyond, said plate being provided adjacent its end with,a

transverse lug adapted to be received in said opening and being furtherprovided' op-' posite said lug with a beveled face adapted to be engagedby the cam face of said locko f said locking member.

In testimony whereof I 'afiix my signature.

FRANK ARCHER.
